It appears that you are encountering an issue with the data validation rule in Aspose.Cells where the maximum value for a whole number validation is not being set correctly for large numbers. Specifically, when you set the maximum value to 10,000,000,000, the corresponding Aspose.Cells.Validation object is returning -2,147,483,648 instead.
This issue arises because the maximum value for a whole number validation in Aspose.Cells is limited to the range of a 32-bit signed integer, which is from -2,147,483,648 to 2,147,483,647. Since 10,000,000,000 exceeds this limit, it cannot be represented correctly, resulting in the incorrect value you are seeing.
To work around this limitation, you can consider using a different approach for data validation. For example, you could implement a custom validation logic in your application to check if the entered value is below 10,000,000,000, rather than relying solely on the built-in data validation feature.
Here is a sample code snippet that demonstrates how you might implement this custom validation:
var workbook = new Workbook("DataValidationIssue.xlsx");
var worksheet = workbook.Worksheets[0];
var cell = worksheet.Cells["A1"]; // Assuming you want to validate cell A1
// Example of setting a value
cell.PutValue(10000000001); // Enter a value greater than 10 billion
// Custom validation logic
if (cell.Value is double value && value >= 10000000000)
{
Console.WriteLine("Value exceeds the maximum limit of 10,000,000,000.");
}
else
{
Console.WriteLine("Value is within the acceptable range.");
}
This way, you can ensure that the values entered into the cell adhere to your specified limits, even if the built-in validation does not support such large numbers.
